Experimental Physics and
Industrial Control System

Hi Jeff,

That does not work for me.

Only when I turn on "nscd" on my linux systems do things work reliably.
When nscd is not running most of the time I get the empty string.



Thanks,
Ernest

Dirk,

I think the IP address would be better than an empty string.

TBOMK, it does return the dotted IP address as a string if the DNS transaction hasn't completed yet. Let me know if that isn’t the case.

unsigned hostNameCache::getName ( char * pBuf, unsigned bufSize ) const

{
    if ( bufSize == 0u ) {
        return 0u;
    }
    epicsGuard < epicsMutex > guard ( this->mutex );
    if ( this->nameLength > 0u ) {
        if ( this->nameLength < bufSize ) {
            strcpy ( pBuf, this->hostNameBuf );
            return this->nameLength;
        }
        else {
            unsigned reducedSize = bufSize - 1u;
            strncpy ( pBuf, this->hostNameBuf, reducedSize );
            pBuf [ reducedSize ] = '\0';
            return reducedSize;
        }
    }
    else {
        osiSockAddr tmpAddr = this->dnsTransaction.address ();
        return sockAddrToDottedIP ( &tmpAddr.sa, pBuf, bufSize );
    }
}

Jeff
